I-UV yokunyanga (UV) intlaka luhlobo oluthile lwentlaka ekwaziyo ukumelana ne-photosensitive enobunzima obuphantsi ngokwemolekyuli.Inamaqela anokwenza ukusabela kwe-UV yokunyanga, njengeebhondi ezahlukeneyo ezingafakwanga kabini okanye amaqela e-epoxy.Yeyona nxalenye iphambili yeemveliso zokunyanga ze-UV (i-UV i-UV, i-inki ye-UV, i-Adhesive ye-UV, njl.
Okwangoku, ii-resin ezinyangekayo ze-UV zasekhaya ikakhulu ziquka i-epoxy acrylate, i-polyurethane acrylic resin, i-polyester acrylic resin, i-amino acrylic resin kunye ne-photo imaging alkali soluble resin.
Iimpawu kunye nokusetyenziswa kwee-resin ezahlukeneyo ze-UV ezinyangekayo
1. I-Epoxy acrylic resin yeyona isetyenziswa kakhulu kwaye esona sixa sikhulu se-UV yokunyanga intlaka ngoku.Ngenxa yenkqubo yayo elula yokudibanisa, umthombo ofanelekileyo wezinto ezikrwada, ixabiso eliphantsi, isantya esikhawulezayo sokunyanga ukukhanya, ubunzima obuphezulu, isicwebezelisi esiphakamileyo, ukuxhathisa okugqwesileyo kweekhemikhali, ukumelana nobushushu obulungileyo kunye neempawu zombane, i-epoxy acrylic resin isetyenziswa ngokubanzi njengentlaka yokukhanya. iphepha elinyangayo, iinkuni, iplastiki kunye neengubo zentsimbi, i-inki enyangekileyo kunye nencanyathi enyangekileyo.Iindidi eziphambili ziyi-bisphenol I-epoxy acrylic resin, i-phenolic epoxy acrylic resin, i-epoxy oil acrylate kunye neentlobo ezahlukeneyo ze-epoxy acrylic resin.
2. I-polyurethane acrylic resin nayo isetyenziswa ngokubanzi, isixa esikhulu sokukhanya okuphilisa i-resin.I-polyurethane acrylic resin isetyenziswa kakhulu kwiphepha elinyangekayo le-UV, iinkuni, iplastiki kunye nentsimbi, ii-inki ezinyangekayo ze-UV kunye ne-UV encamathelayo enokunyangeka ngenxa yeempawu zayo ezigqibeleleyo ezibanzi, ezifana nokunganyangeki okugqwesileyo kunye nokuguquguquka, ukuxhathisa okulungileyo kwikhemikhali, ukumelana nempembelelo kunye neempawu zombane. ifilimu ephilisiwe, kunye nokunamathela kakuhle kwiiplastiki kunye nezinye izinto ezincinci.Iindidi eziphambili zinuka kunye ne-aliphatic polyurethane acrylic resin.
3. I-polyester acrylic resin nayo isetyenziswa ngokuqhelekileyo intlaka yokunyanga ukukhanya.Ngenxa yokuba i-resin inevumba eliphantsi, ukucaphuka okuphantsi, ukuguquguquka okuhle kunye nokumanzisa kwe-pigment, ihlala isetyenziswa kwipeyinti yombala yokunyanga ukukhanya kunye ne-inki yokunyanga kunye ne-epoxy acrylic resin kunye ne-polyurethane acrylic resin.
4. I-amino acrylic resin idla ngokusetyenziswa kwiingubo ezinyangekayo ze-UV kunye ne-inks ezinyangekayo ze-UV kunye ne-epoxy acrylic resin kunye ne-polyurethane acrylic resin ngenxa yokuxhathisa ubushushu obuhle kunye nokumelana nemozulu, ukuxhathisa okulungileyo kweekhemikhali kunye nobunzima obuphezulu.
5. Ifoto yomfanekiso wealkali enyibilikayo yintlaka esetyenziswa ngokukhethekileyo kwi-inki yokujonga ifoto yokujonga ulwelo.Iqulethe amaqela e-carboxyl kwaye inokuphuhliswa kwaye ifanekiselwe ngamanzi e-alkaline.Ifilimu ephilisiweyo ineempawu ezintle zombane, ukuchasana kweekhemikhali kunye nokumelana nokushisa.Ezona ndidi ziphambili yi-maleic anhydride copolymer kunye ne-epoxy acrylic resin eguqulwe nge-maleic anhydride.
